CAN
The CCpilot VC device contains two CAN ports that meet the CAN ISO 11898 2.0B specification.
Each CAN port is galvanically isolated from chassis ground and is tolerant for bus short-circuits. There
is no device-internal CAN bus termination; therefore bus termination must be applied externally.

USB
The CCpilot VC contains two USB ports. One port is located in the multipin connector 1 and function
as a host interface. This port can be used for application for data transfer or the connection of a
peripheral such as a mouse or keyboard.
The second USB port which interface through a micro USB connector is located under a cover on the
backside of the device. This port supports an USB OTG interface, i.e. acting as both host and device
interfaces. Using the port in USB device mode, it’s only for enable OS updates through a connected PC
with appropriate tool installed. In USB host mode, it supports the same functionality as the USB host
port in the main connector.
Note, the sealing property of the unit is affected when accessing the second USB port located under the
hatch.
Due to limitation in the multipin connector specification, USB data signal integrity cannot be
guaranteed with higher speeds than full-speed USB (12 Mbps). Though, hi-speed operation is
supported by the USB host controller.
The USB ports can supply up to 500 mA each. The USB ports are internally over current and short
circuit protected. Shielded cables shall be used to ensure reliable communication and electromagnetic
compliance. Depending on installation the shield could be connected to USB ground or left
unconnected on the Deutsch DTM-12 connector, i.e. CCpilot VC, side of the cable.
